Audio click retrigger vca

#1

Hi there!! I'm having a hard time trying to finish my first patch. (Maybe I started with a to complex one for a newbie) any way....
Is there a way to avoid audio clicking when retrigger a vca? The problem is than if I set a long decay and a note start before the decay ends I have a horrible click. I try the smooth object and also changing my Decay envelope for a attack/decay envelope (cause I thought maybe the click was on the attack of the note but the click seems to appears when I interrupt the tail of the note)
I forgot to say than I have to use the "env/line 2 m" object cause is the only envelope than have only attack decay with trigger input(not gate) and modulation inputs for both attack/decay parameters.
Any idea will be very appreciated as I'm stock .

tiar/gain/DCA as a substitute for the vca should work.

#3

Great! I will try it as soon as I can. Thank you very much!

#4

Not working! Still have this clicks.
I forgot to mention it happens when I sample a sine wave. With the majority of samples I record I can't not appreciate the clicking but with the sinewave it's horrible.

#5

what do you mean by sampling a sine? can you post the patch?

#6

Sorry I didn't explain the hold patch. I have a patch than samples from audio input of the Axoloti core (I normaly plug a synth or a radio or any other instrument) I control the hold patch with Twister Midi Fighter(it's midi controller with a very simple sequencer) . The patch it's based on a tutorial from Matthew Tyas https://youtu.be/52-DvFcg1Q8

I add filters,distortion,delay,reverb and LFOs and Envelope for modulation so right now the patch is quite messy.
I will try to clean it a little a post it here so you can check it. Or maybe it's better idea if I make a simple version of it(cause it's a really kaotic patch right now)

#7

if you can make a simple version that exhibits the problem, that would be best!

hi there!
WHY vca CLICKING.axp (6.1 KB)

this is just the sampler and the vca (I add toggles so you don't need to plug any midi controller)
first toggle REC audio
second toggle PLAY audio
the DIAL controls DECAY
the last Toggle select between the two different VCA types.
try sampling a SINEWAVE from any SYNTH and play with long decay times you will ear what I mean.

I been trying to make this VCA work with my patch but can't find a way to avoid this ugly clicking.
I am thinking than maybe the "problem" can be solved by stoping and retriggering the sampler (table object) with each note I play (i haven't really try it yet)
But I'm afraid it's not going to be possible with my patch cause I'm really pushing the limit on SRam.
It will be great if I can make the VCA work ...
Any suggestions wil be very appreciated!

try this noCLICKING.axp (4.6 KB)

#11

Thanks for trying!!
Unfortunately its not making any difference with the clicking. for what I see the changes you made are in the "recording part" of the patch. and thats not the problem. The clicking appears when you retrigger (play) the sample before it finish ... I will try to translate your changes to the "playing part" on the patch. just to see what happens

EDIT: I just apply it to "play part" of the patch and its not working for what Im needing. Cause if I stop the note when releasing the toggle I "loose" the envelope so no tail,JUST a drastic cut and that means a clicking.

what im trying its to close envelope every time I retrigger it... even if the tail of the envelope still not finished.
Or maybe I need another way to solve the problem...another approach.

You're right, I completely overlooked the stopping part... basically you should have a fade out before the reset.I think you can do it by having the play button trigger a fade out first, and later (with a delay) the table/play and the envelope- hope this helps!

#13

Is a zero crossing detector needed here?

#14

suggested already...did not work out apparently

#15

Sorry not sure what a "zero crossing detector" is... Is that the DCA lokki was suggesting me?

#16

Yes, tiar/gain/DCA only changes gain when input signal is crossing zero, which is often the solution for clicks in the audio.

#17

Did anyone actually use the tiar/gain/DCA object with success? I tried a little with both the interpolated and not interpolated version and it always clicked, in the OP patch and also in my loopstation patch, where I ended up using the fade in/fade out approach I tried to explain above with the standard VCA. I mean it clicked also during those shorts fade in/fade out that worked with VCAs...
